I have long admired the way in which artist Joshua Sofaer approaches the participatory aspect of his practice. It is always very considered whatever mood it invokes – philosophical, humorous, inventive, bold, reflective, excavatory. Or cheekily clever, as in this nugget of a film below where he explains the term ‘Live Art’ on London’s Oxford Street. It’s clear to see that people on the street are engaging with him. But why? You’ll need to watch until the end of the film to find out.
